alil whom it may concern Be it known that I, OSCAR Znnx, a sub ect oi? the Emperor of Austria, residing at ating with an opening in the base of the cup-- to constitute a needle valve. Oil" may be admitted through the top of the cap into the cup and then the rotation of the cap opens the valve to discharge such oil into the engine. A suitable spring detent device is provided between the cap and cup, whereby inadvertent displacement of the cap is pre- 25, vented. My invention is hereinafter more 'fully explained and its essential characteristics 1 summarized in the claims;'

In the drawings,

central section thereo P1 3 is a plan; Fig. 4 is' across section of the cap below its detent spring, lookin u wardly; and Fig. his a perspective oft e etent spring'shown. As shown in the drawings, 10 represents the clip proper, which may he a body made of Figure 1 is a side eleva- 2 is a vertical pressed metal, or otherwise formed, as desired. This cup has an angulariexterior 11,

' below which is an externally threaded portion 12, and above the angular portion is-a flaring portion 13, above which is a wall 14 with an external thread. 'A continuous ch'amber is provided by the various parts mentioned.

" 2O designates the cap. This has a verticalwall 21' provided with an internal: screw thread 22 adapted to screw onto the threaded portion 14 of the cup. Suitableknurling 23 on the cylindrical portion of the cap provides convenient means for turning it.

by the cap. At its lower end it is formed comically, as. shown at 32, and cotiperates with a conical seat in'the lower portion of the chamber 15 in the cup. Normally this COIllClll'PQlIlt 32' rests snugly inits seat, so that the exit of oil through the opening 16 is prevented. Accordingly, the cup may be filled through the opening 24 in the cap" thereafter the unscrewing rotation oi capwithdraws the rod 30 from its allowing a measured quantity of oil to into the en I To'efl'ect vely look at the. same time allow a suflicientforce to rotate the cap as desired, I provide a very simple and eifective sprmgdetent mechanlsm, which I will now describe. i

- The valve rod 30 near its upper end has a collar 34. Surrounding the rod and.

clamped between this collar and the under face of the cap, isasprin have the form shown in I' igs. 2, 4 and 'o. As there shown, the s ring consists of a disk havingythe horse oe-shaped opening 41, to provide a spring ring 42 extending freely outside of the collar 34, this ring be ng bent downwardly at its farthest point, making a projection 43. This proection is adaptedto coiiperate with notches 17 m the upper edge of the wall of thebase. The spring 40 normally maintains the ro and the" the cap to thecup 15 40 which may jection in engagement with ,one of t ese,

notches, and thus locks the cap to the cup,

the spring lock out o the notches and enables the cup to rotate. A suitable opening 45 in the springI disk 40 registers with the e cap and thus allows the passage-of oil.

It will be seen that my primin cup is extremely simple in construction an is neat in appearance. It results in keeping the opening 16 normally tightly closed. Oil may be admitted whenever desired through the opening 24. When the cup is filled t backward rotation of the cap allows the contained oil to pass into the engine. Whenever desired, is e cap with its rod may latter used as a funnel for transmitting'oil be removed entirely from the cup, and the a cap threading on the cup and having a central rod secured thereto and cooperating with a seat at the base of the cavity in the cup, and a spring detent carried by 'the cap within the same and coacting with the cup, substantially as and for the purpose set forth.

2. In a device of the character described, the combination of a cup having a cavity and having an external thread, acap having a wall with an internal threadscrewing onto the external thread, a central rod rigidly secured to the cap and cooperating with a seat at the base of the cavitvinthe cup, a washer-like spring surroun ing the rod and having a downward projection, and notches in the upper edge of the cup with which such projection may coact.

3. In a device of the character described, the combination of a cup having an exter-' nal thread and a notched upper edge, a

cap having a Wall internally threaded and screwing onto the. cup, a central rod rigidly secured to the cap; and acting as a valve on a seat near the lower end of the cup,

a spring within the cap surrounding the r rod and rotatable therewith and clamped between a shoulder on the rod and the head ofthe cap, said spring having a downward projection cooperatingiwith the notches in the upper edge of the cup.

4. In a device of the character described, the combination of a cup havin an exter nal thread, a cap having a wal with an internal thread screwing onto' the external thread, a central rod having its upper end upset in the cap and pqiiperating at its lower end with a seat atithe base of the chamber in the cup, a spring detent for" locking the cap to the cup, comprisin a spring clamped by the rod'to the hea of the cap and rotatable therewith, said spring having aprojection and there being notches in the upper edge of the cup with which such projection cooperates.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
